A bit unbalanced but a lot of fun.

I love single-screen platformers, but you don't really get those outside of retro throwbacks these days. This is definitely a retro throwback, but it's a good one.

I played the coop campaign, which I found out later is apparently significantly harder than the single-player campaign. It has different level designs and puzzles that require both players to complete.

The difficulty curve is a bit all over the place; sometimes hard levels are followed immediately by incongruously easy ones, and I found the first boss to be many times harder than the much more fun to fight second boss. Once I unlocked the unlimited retry option the difficulty felt a lot more manageable though, and coordinating with a local player to solve some of the toughest puzzles was really satisfying.
